These plants receive residential, commercial, and sometimes industrial wastewater that may contain PFAS. Conventional wastewater treatment plants are not designed to treat for PFAS, therefore PFAS may pass through the treatment system to surface waters (i.e., lakes, rivers, etc.) and groundwater. EGLE is actively working with these wastewater treatment plants to address PFAS.
For more information, please see the Wastewater Workgroup page.

Muskegon County operated the former Whitehall Wastewater Treatment Plant (WWTP) located at 2000 Holton-Whitehall Road from 1972 until April 2003. Treatment included an equalization basin, clarifier with sludge removal and lime conditioning, aeration basins, an aerated storage lagoon, slow-rate infiltration and spray irrigation. A groundwater collection system was used to collect infiltration/irrigation water and discharged to the White River. In April 2003, all Whitehall area wastewater was sent to the Muskegon County Wastewater Management System Metro WWTP and the Whitehall WWTP was decommissioned.
In the 1970s and 1980s, groundwater at the former Whitehall WWTP was contaminated due to lagoon leakage (i.e., a discharge of wastewater from the lagoon to the groundwater through the bottom and sides of the lagoon) and wastewater infiltration/irrigation. The source of contamination was an industry's discharge to the WWTP. The County currently operates a groundwater extraction system on-site and discharges the groundwater to the White River. The discharge is monitored in accordance with a National Pollutant Discharge Elimination System (NPDES) permit issued to the County.
In 2018, the County submitted a request to discontinue the groundwater extraction system. As part of the closure review process, EGLE requested the County conduct additional groundwater monitoring, including for PFAS due to the historical industrial discharges to the former Whitehall WWTP. Groundwater monitoring was completed in fall 2021. PFOA was detected in 11 monitoring wells in exceedance of groundwater criteria.
Groundwater flows to the northwest on the west side of the site towards the White River, while groundwater on the east side of the site flows to the northeast towards Silver Creek.

The County has routinely monitored residential wells surrounding the site for non-PFAS chemicals of concern, the majority of which are located along Mill Pond Trail and Silver Creek Drive. Whole house carbon filters and bottled water have been provided to 15 homes that have previously shown impact from non-PFAS contaminated groundwater at the former Whitehall WWTP. EGLE will continue to work with the Michigan Department of Health and Human Services (MDHHS), and Public Health Muskegon County to evaluate residential wells in the area and expand residential drinking water well testing if determined to be necessary.
EGLE will continue to work with the County to define the extent of PFAS contamination in the groundwater and identify potential downgradient receptors.
